How far did you get the hub back on did you use an install tool to seat it all the way on? If it's not all the way in you might have only messed up the first couple of threads

Shops everywhere are going to tell you to pull the crank - they want your money. I would try helicoiling or use a Timesert - either one will work fine for that application.

As far as getting the bolt out is concerned, I'd try this. Take off the pulley (the 3 bolts) so all you have left is the crank hub and the stubborn bolt. Using a hub puller, pull the hub off of the crank snout (as far as it will go). Since the bolt is still in the way, you might need to stack some washers and get creative to give the puller something to push against. Once you have the hub out as far as it can go, you can use the crank hub as leverage to wiggle the bolt back and forth and, depending on how far you get it out, pry against the back of the hub to remove the bolt or, even better, use the puller to pull the hub AND the bolt out.

Once it's out, just helicoil or Timesert. Done.

With the bolt being loose and just snugging up the get loose again even on the removal, I hate to say it but you would be better off just giving it to a shop to have them remove the bolt for you. there is a strong chance YOU will further damage the threads and/or crank.

Will I have to remove the hub to install the Helicoils or Timesert?

Yes indeed.

Think about this: you could spend a couple bucks doing the helicoil/timesert deal and if it works (which it will), it will have only cost you vehicle down-time and the cost for a drill bit and the helicoil/timesert kit. If you take anyone's advice about replacing the crankshaft, you're looking at a rebuild which will run you in excess of $1500+.

Which makes the most sense?

And your assuming he has the skills and tools to perform this task. if he isn't comfortable to drill his crank then see if there is someone who has the experience, tools and skills to perform the task at hand. I would never tell someone to perform this task not knowing the skill level of the person I'm talking to. take into consideration the original task that lead to this and how it got screwed up to begin with.

I didn't think cleaning up a hole with the proper sized drill bit takes an immense amount of mechanical ability.

I guess it's up to him if he wants to spend the money on a tow truck and a shop to do it. I'm suggesting the cheapest alternative - that's all.

It never hurts to know all of your options.
